DC resistor air element 1.0 or 0.8 Ohm
DC resistor air element 1.0 or 0.8 Ohm

This single resistor air elements can be used on 12 & 24V battery systems to divert surplus power (up to 1kW each) to air heating.

  • 1.0 Ohm
  • 0.8 Ohm

The power dissipated in a resistor is calculated as follows:

(fully charged battery voltage)^2 / resistance

Also check that the maximum current draw does not exceed 30 amps.

Current =  Power/fully charged battery voltage

Power (Watts)
Ohms 14V 28V 56V
0.80 245 980 n/a
1.00 196 784 n/a



Please note: Must be mounted on a steel backing with suitable protection to eliminate any fire risk.
